I am almost certain that you may not change the mode of the computer UEFI vs BIOS during a task sequence. The mode must be set before the task sequence starts up- in a pre-execution script for instance.
Secure boot, you could enable at the end once Win10 is installed.

I want to change this to UEFI with SecureBoot when we deploy Windows 10. During the task sequence, if I use Dell's tool to change BIOS to UEFI and enable SecureBoot, do I need to reboot before I install Windows?
